At first I thought, great deal. Then I started reading the reviews and looking at the user posted pictures. Most reviews all claim this is a not an official Apple cable, and the very top review scarily says: "THIS CAUGHT MY COMFORTER ON FIRE!"
How can this listing be claimed sold officially by Apple[1]? Doesn't Amazon verify name brand sellers?

Some bad actors will sell counterfeit products through Amazon to "launder" it. Other times, people will buy a real product and "return" it (sending a fake one back), which results in Amazon stocking it.
tl;dr Never shop on Amazon unless you have to. Best Buy, Target, NewEgg, MacMall, etc. tend to have similar prices and aren't as anti-consumer.
